Hello,

I have to 'speak' with a web service that only handles gzip compression. The zstream TCompressionStream only does deflate.
Any hints according to zlib derivates to use windowbits = 15+16 do not work with zstream or paszlib because this part of zlib is not implemented here. It seems that there is a solution with indy using the http component and TIdCompressorZLib as compressor. But I just switched from Indy to synapse because indy has no openssl 1.1 support, which is needed to support actual Linux distributions.

The only ways I see at the moment seems to be ugly: Using the external zlib runtime libraries or
creating for every request a temporary file in order to use the zstream Tgzfilestream.

Is there no gzip stream library for lazarus ?
